LOS ANGELES - Applied Underwriters Inc.'s captive reinsurer is appealing a California federal judge's confirmation of an arbitration award requiring it to pay more than $500,000 to a former policyholder who participated in the EquityComp workers' compensation insurance program.

According to a Feb. 22 notice of appeal, Applied Underwriters Captive Risk Assurance Company Inc. asked the 9th Circuit U.S. Court of Appeal to review an order that found the arbitrator did not manifestly disregard the law in issuing the award.
